Sir William Bruce of Kinross, 1st Baronet (c. 1630 – 1710), was a Scottish gentleman-architect, "the effective founder of classical architecture in Scotland," as Howard Colvin observes. As a key figure in introducing the Palladian style into Scotland, he has been compared to the pioneering English architects Inigo Jones and Christopher Wren, and to the contemporaneous introducers of French style in English domestic architecture, Hugh May and Sir Roger Pratt.
Bruce was a merchant in Rotterdam during the 1650s, and played a role in the Restoration of Charles II in 1659. He carried messages between the exiled king and General Monck, and his loyalty to the king was rewarded with lucrative official appointments, including that of Surveyor General of the King's Works in Scotland, effectively making Bruce the "king's architect". His patrons included John Maitland, 1st Duke of Lauderdale, the most powerful man in Scotland at that time, and Bruce rose to become a member of Parliament, and briefly sat on the Scottish Privy Council.
